如何使用一个 JTable 显示另一个 JTable 的信息

问题描述

如何通过选择 Jtable 行获取信息，然后将不同表中的相关信息提供到另一个表中？我想显示我的发票信息，一旦我点击一个，我想显示与其相关的客户和产品。

try {
            Connection connection;
            connection = DriverManager.getConnection(DATABASE_URL,"root","");
            Statement statement = connection.createStatement();
            String query = "SELECT I.idInvoice,C.idCustomer,C.FirstName,C.Surname,C.Phone,C.Street,C.City,C.County,C.Eircode,P.idProduct,P.PName,P.Price,P.Brand,I.QuantityOrder\n" +
                    "FROM `Invoice` I \n" +
                    "JOIN `Customer` C on I.idCustomer = C.idCustomer \n" +
                    "JOIN `PRODUCT` P on I.idProduct = P.idProduct LIMIT 0,1000";
            PreparedStatement pstat = null;
            ResultSet rs = statement.executeQuery(query);
            // Column name array
            String[] columnNames = {"idInvoice","Date","QuantityOrdered","idCustomer","idProduct"};
            String[] columnNames1 = {"idProduct","pName","Brand","Price","Quantity"};
            DefaultTableModel tableModel = new DefaultTableModel(columnNames,0);
            DefaultTableModel tableModel1 = new DefaultTableModel(columnNames,0);
            // Get data from database
            while (rs.next()) {
                String idI = rs.getString("idInvoice");
                String idC = rs.getString("idCustomer");
                String idP = rs.getString("idProduct");
                String date = rs.getString("Date");
                String qOrdered = rs.getString("quantityOrder");
                // Row data
                String[] data = {idI,date,qOrdered,idC,idP};
                // Add date to rows
                tableModel.addRow(data);
            }
            // JTable creation and customization
            table = new JTable(tableModel);
            table.setPreferredScrollableViewportSize(table.getPreferredSize());
            table.setFillsViewportHeight(true);
            pTable.add(new JScrollPane(table),BorderLayout.CENTER);
